How the 60-530-N1MAS model number is decoded
In the large-bore 6000-series, the bore is written directly after the slash as 530 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 530×780×112 mm (20.866×30.709×4.409 in) with a 125.0 mm radial section height, C 650 kN, C0 1270 kN and Pu 20.8 kN. The open 60/530 N1MAS carries no shields or seals and relies on application lubrication and external sealing. The N1MAS suffix identifies the machined brass cage execution (special cage variant for this large thin-section size), a separate order number from the pressed-steel version. Limiting speed 1200 r/min, catalogue mass 185000 g.
Typical equipment & failure modes
Common applications
- hoists and winches
- industrial fans and blowers
- mill and kiln auxiliaries
- pulp and paper machinery
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- Catalogue ratings for 60-530-N1MAS (C 650 kN, C0 1270 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- Do not preload 60-530-N1MAS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- The N1MAS execution of 60-530-N1MAS is a special machined-brass cage variant listed in catalogue 17000 for the largest thin-section sizes; confirm the exact cage feature set with SKF when ordering and servicing.
- The N1MAS suffix on 60-530-N1MAS denotes a machined brass cage: it is the choice for high speeds, marginal lubrication and shock/vibration duty, and it is temperature-tolerant where polymer cages are not — the 185000 g quoted mass includes the heavier cage.
- Open 60-530-N1MAS needs external sealing at the arrangement level; in dusty housings its life depends entirely on those external seals and the regreasing schedule.
- Plan a relubrication interval for 60-530-N1MAS; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
Frequently asked questions
What are the dimensions of 60-530-N1MAS?
The SKF 60/530 N1MAS measures 530 mm bore × 780 mm OD × 112 mm width (20.866 × 30.709 × 4.409 in), mass about 185000 g. It is open, with no shields or seals.
Why is there a slash in the designation 60/530 N1MAS?
The slash writes a bore that falls outside the two-digit code table: 60/530 means 530 mm bore. The site slug 60-530-N1MAS replaces the slash with a hyphen.
Which fits should I use for 60-530-N1MAS?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 780 mm housing; reverse the interference if the outer ring rotates.
How heavy is 60-530-N1MAS?
Catalogue mass is 185000 g for 60/530 N1MAS; seal and cage executions of the same envelope differ by a few grams.
